1401  Economy / Web Wallets / Re: Is it possible for a single wallet to access all 3 Bitcoin address formats? on: July 03, 2020, 07:03:38 AM
You can use the offline version of https://iancoleman.io/bip39/#english to generate a bip39 seed (or any other tool for that matter).

If you import this seed, click on "options" and mark that the seed is bip39, the next step of the wallet restore gui will show this menu:



One seed, 3 wallets Wink

If you want to learn more as to why electrum does the things it does when it comes to bip39 seeds, here's an interesting article: https://electrum.readthedocs.io/en/latest/seedphrase.html?highlight=bip39
1402  Bitcoin / Bitcoin Discussion / Re: Blockchain.com experience and issues? on: July 03, 2020, 06:54:46 AM
So my steps were as follows:

1. I set up a new wallet on my Ledger S.
2. I recovered my Blockchain.com wallet in Electrum with the seed
3. I then transferred the recovered coins from Electrum to the new wallet on my Ledger S.
4.  All my coins are now in my Ledger S and I no longer plan to ever use Blockchain.com again! Smiley
5.  If I decide to store additional coins on Electrum then I understand that I need to generate a new wallet.

Am I good?

In terms of an exchange to buy/sell coins in the future. Would everyone recommend CEX? It seems like a good platform in my experience so far.  If there is another one that is better (by 'better' in my instance I would value user interface, speed, fees and simplicity, mobile add etc)


Completely correct Smiley
About step 5: do realise there is hardly no upside to storing funds in a "normal" electrum wallet... Some people (including myself) do use electrum together with their hardware wallet, since the gui offered by most hw wallet vendors has a feature set that is inferior to electrum... But a "plain" electrum wallet only has one upside: it can be used if you don't have your hardware wallet at hand... But that's about it.

About the exchange, i used binance one or two times in the past and i was happy with them... I've used Litebit aswell (once), but their fees were on the high side.
I'm not a frequent trader tough, so maybe somebody else will give you better advice.
1403  Economy / Web Wallets / Re: Is it possible for a single wallet to access all 3 Bitcoin address formats? on: July 03, 2020, 06:32:50 AM
I know coinomi does the same, but personally i wouldn't use them. A mobile wallet that has been surrounded by a lot of discussions about safety and wether or not the sourcecode they share is their actual current release... Not for me.

You can have one seed and use this one seed to create a legacy, nested segwit and native segwit wallet in electrum tough... You don't need 3 seeds, but you'll end up with 3 wallets. This being said, you're able to open 3 electrum instances at once... So you can have one seed => 3 open wallets.

Not exactly what you were aiming for tough... Why do you need the 3 "types" of wallets?
1404  Bitcoin / Bitcoin Discussion / Re: Blockchain.com experience and issues? on: July 02, 2020, 01:10:26 PM
Excellent! Thank you all for turning around a pretty negative experience to a positive one.

James.

No problem... I really hope you stick around.

By the way, a quick google turned up this link:
blog.blockonomics.co/how-to-restore-blockchain-com-wallet-into-electrum-f593ec79ab3d?gi=ed73891cfd60
I can't really endorse it, since i haven't tried the steps myself... But a quick browse doesn't show any malicious steps, so worst case scenario it just doesn't work (no harm done).

don't forget: download electrum from it's OFFICIAL repo, check the signature, encrypt your wallet and make sure your computer is clean.
Being your own bank is hard work Smiley
1405  Bitcoin / Bitcoin Discussion / Re: Blockchain.com experience and issues? on: July 02, 2020, 12:56:46 PM
Ok Bitmover I have checked the address and the coin is there!  Grin

I guess I still have the same issue that I can't access it as its not in my wallet and Blockchain.com are basically not responding.

What is my next move?  

....as an aside, Its a sad state of affairs when you get world class (and instant) support from a open forum and zero support from the platform you are actually paying to manage the transaction.

James.

Yup... To be honest, a lot of centralised services (like exchanges) are known to have sloooooow support. Blockchain is not an exception.

My next step would probably be to download electrum from it's official repo, check the signature (ThomasV signs his builds), the import your seed into electrum (there are some caveat's when you try to do this tough. But since i don't have a blockchain seed at hand, i'm not able to write down the complete procedure for you).
Once your unspent outputs are visible within electrum, i'd probably empty out my wallet by moving all funds onto your ledger... Really, there is no need to use a web wallet if you own a hardware wallet. I only use a mobile wallet when i go out to a place that has a high chance of accepting bitcoin as payment, the rest of my funds are always safe on my hardware wallets.
1406  Bitcoin / Bitcoin Discussion / Re: Blockchain.com experience and issues? on: July 02, 2020, 12:46:26 PM
Happy to see you got your seed...

The "best" option would be to use the seed phrase to restore your wallet in a decent desktop wallet... That way you at least have some idear of what might have happened...
1407  Bitcoin / Bitcoin Discussion / Re: Blockchain.com experience and issues? on: July 02, 2020, 12:21:30 PM
Hi,

First of all, it's a petty your first experiences with bitcoin are rather negative.
To be honest, i always try to steer people away from web wallets, like blockchain.com... These services are high-risk, since you're not the only one in controll of your keys, you're not the only one in controll of your funds. Blockchain saves an encrypted version of your wallet on their servers. They say you're the only one that can decrypt said wallet, but it's hard to check this statement.

Case in point: if you have issues like the issue you describe, you NEED support from blockchain.com. If you'd have used a decent wallet, you could have restored your wallet from backup or seed.

First things that pop to my mind when i read your story:
  • Did you, by any chance, save the seed words for your blockchain wallet?
  • Are you certain you only have one wallet?
  • Are you certain you didn't fall victim to a phising attack?
  • Are you certain your computer is clean? No virusses or malware?
  • Were you using the web client, or the mobile client?

Check Scaleway.

That's a good tip... 75 Gb free, then 1 cent/gb/month... So about 4€/month would suffice.
Thanks!
1409  Other / Off-topic / cheap storage on: July 01, 2020, 09:49:49 AM
Hi guys,

A bit offtopic, but since this is more or less the only forum i'm using, i still hope to get some non-spam replies.

I'm going to upgrade the proxmox environment on my dedicated host. Since i'm moving from proxmox 4.x to 6.x, odds are i'll break something and i'll have to restart from scratch.
It's pretty easy for me to backup my containers as a tarball, so in case something goes wrong, i can scratch the host and restore my containers.

This is where it's becoming problematic: my biggest container is > 400 Gb and i only have about 200 Gb free space on my device.

I was thinking about getting some free or payed cloud storage that supports mounting on my linux server, mounting said storage, defining the mointpoint as directory storage within proxmox, then create backups of my vm's using this storage. My proxmox instance will think it's back-upping to a local store but in reality it'll be back-upping to external storage.

I can then download the backups to a local disk on my nfs at home.

However, i'm struggeling to find a suitable storage provider. These guys charge an arm and a leg... I need ~0.5 Tb storage for one or two days, i'm not going to pay $50 to transfer 1 or 2 Tb while actually using ~0.5 Tb for one or two days...

Does anybody know a storage provider that provides nfs, sftp, ftps,... >0.5 Tb, short term contracts for a reasonable price?
A VPS provider with >0.5Tb HDD would also be perfectly fine, as long as the price is very reasonable.

Or does anybody have any other idears of how to solve this problem? If this was a machine from work, it would have been a 10 minute task, since i would have created a netapp volume, mounted it, and got everything done... At home, for private use, it seems everything is more difficult.
1410  Bitcoin / Electrum / Re: Electrum Lightning Demo on: July 01, 2020, 06:34:18 AM
Just as a general heads-up...

It seems like ThomasV is now actively compiling and signing electrum 4.x beta releases Smiley

https://download.electrum.org/4.0.0b1/

I'll keep my repo open, but it might be a good idear to get your builds directly from ThomasV's repo!
1411  Bitcoin / Development & Technical Discussion / Re: New Testnet Faucet (tBTC, tBCH, tLTC, tDOGE, tDGB)! Testnet-Faucet.com! on: June 26, 2020, 01:38:44 PM
Glad to see more tbtc faucets Smiley

I wanted to check it out, but it's not only the faucet that's down, but your complete host (or so it seems).

As for preventing abuse, i use a combination on my faucet:
  • A captcha (not recaptcha)
  • an ip blocklist
  • a "smart" payout script.... I bulk send payouts once per hour, and the script handling the payouts checks for a limited amount of parameters before adding payment to the bulk list. If abuse is detected, the user's ip is added to the blocklist and the payment is deleted without payout
1412  Bitcoin / Hardware wallets / Re: How to verify a Trezor Message if you don't own Trezor HW wallet? on: June 26, 2020, 01:10:56 PM
You're more or less correct...

Here's some extra info by a Satoshilab employee:
https://www.reddit.com/r/TREZOR/comments/8vyenv/please_help_cannot_verify_trezor_signed_messages/

Trezor is open source, so even without the above post, it *should* *theoretically* be possible to create an application outside trezor's wallet to verify messages signed with a trezor HW device (since, if you'd read the sourcecode, you'd probably find how trezor handles the signature verification). This being said, i don't know any of these tools...

IF you're ever stuck with a signed message you can't verify, don't hesitate to PM me. I have a couple trezor's laying around and i don't mind verifying a message now and then.
1413  Bitcoin / Bitcoin Discussion / Re: What is Bitcoin Halving on: June 26, 2020, 09:56:52 AM
In 2009, the system started at 50 coins mined every ~10 minutes. Two Three halvings later, 12.5 6.25 bitcoins are currently being dispensed every ~10 minutes.


Fixed that for you...

Really... Same advice i've given before: Learn, read, ask questions, have fun, communicate,. But don't try to educate others about something you haven't mastered sufficiently yourself.
1414  Bitcoin / Bitcoin Discussion / Re: What is Bitcoin Halving on: June 24, 2020, 01:15:12 PM
I don't know where to start here... Your post is full of half-truths and contradictions...

For example:
  • blocks aren't created every 10 minutes. The difficulty is adjusted every 2016 blocks so that the average time between two blocks is ~10 minutes if the hashrate would stay the same as the previous 2016 blocks (at least, under normal circumstances)
  • the halving isn't every 4 years, but every 210.000 blocks
  • you're saying the price goes up AND down after the halving in the same sentence
  • there is no technical correlation between the halving and the price, only an economical one (and even this is debatable)
  • halving something IS reducing it... So when you say "halved or even reduced" you're basically repeating yourself (albeit, the first time you're giving more info than the second time)

Want my advice? Read, learn, listen... Ask questions (sure), but don't write "tutorial"-style posts on a subject you don't have enough knowledge about...
1415  Bitcoin / Development & Technical Discussion / Re: can I generate my own Bitcoin Adress? on: June 24, 2020, 11:27:50 AM
Do not get attached to your addresses. You should use a new address for each transaction. Just a small tip to stay secure Smiley

This is true because of 2 reasons:
  • You'll decrease your privacy if you re-use your address
  • As soon as you spend an unspent output funding your address, your public key is included into the spending transaction. It's not a problem per sé, but it would make the theoretical chance of somebody finding your private key a little bit bigger... Still the odds are incredibly small (small enough to say they're ~0). So, in reality, i wouldn't worry about this, it's just that the theoretical odds have increased, but not enough to start worrying

This being said, vanity addresses usually do get re-used. For example, i re-use my vanity address all the time, i do coinjoin or mix most of my funds before i transfer them to my hardware wallet tough. And i don't really care for the fact my public key is known...

The halving just officially happened! Happy Halving everyone!

euhm... you're late for the party i guess?

The halving happened at the 11th of May, about ~1,5 months ago...

Here's a quick guess, you use Internet Explorer.

1417  Bitcoin / Project Development / Re: Is there a theoretical possibility of recovering "burnt" Bitcoins in the future? on: June 22, 2020, 12:57:02 PM
Well, miners won't be able to recover those funds, unless the protocol changes (and i don't think there'll ever be a consensus about stealing utxo's that have been sitting in the utxo db for to long).

There is a theoretical possibility of a collision (somebody brute-forcing, or accidentally stumbeling upon the private key belonging to the public key hash that was said to be the burn address), but the odds are sooooooooo small, in reality you can say they're 0. Things do change if someobody actually created a private key => public key => address, then convinced people that it was a burn address, while in reality keeping the private key... But that's just fraud, not a real burn address
1418  Bitcoin / Bitcoin Discussion / Re: Special addresses on: June 22, 2020, 12:53:51 PM
To be honest, i don't really see why this address would be special...
It would take a very short time to generate several of these addresses, then make sure there's only one UTXO left funding said address with a predefined amount of sat's.

It might be more interesting to find the vanity addresses that actually belonged to certain people, or that were used in certain events?
1419  Local / Off-topic (Nederlands) / Re: Bitcoin.be on: June 18, 2020, 12:06:26 PM
Ik hoop dat het Nederlands op je website beter is dan hier.

In elk geval zou ik er niet aan beginnen. Er gaat veel tijd in en meer dan een paar centen of enkele shitcoins ga je er niet aan over houden.

De hype is al een tijdje geleden neergedwaald. Je zult het zelf snel merken.

Ik heb héél even op de link in de OP geklikt, het nederlands op de site zelf is een pak beter... In die mate zelfs dat de tekst op de site onmogelijk door de OP kan geschreven zijn.

Voor de rest vond ik de site vrij gewoontjes. Ik heb de eerste 5 artikels gelezen:
  • Gratis Bitcoin: dit artikel zegt helemaal niks, en beloofd ook nog eens iets wat te mooi is om waar te zijn... Ik hecht er geen geloof aan
  • Freebitco.in werkt echt: dat had iedereen je kunnen zeggen. Zie dit artikel als een makkelijke manier om refferals binnen te halen zonder waarde toe te voegen
  • BitFun.co werkt !: Tja, de volgende faucet maar weer? Als je zou uitrekenen hoeveel je met een faucet "verdient" kan je véél beter de raad geven om een studentenjob bij de McDo te beginnen en met je minimumloon crypto te kopen... Véél efficienter
  • Mini n gC -- p a g  -  y: Echt waar? Een ponzi promoten? Deze setup is zoooo overduidelijk een scam dat ik hun naam zelfs niet volledig wil uitschrijven (om geen reclame te maken)
  • Artikel over phoneum zonder titel: ik heb in een ver verleden deze "mining" app eens op een oude android phone gezet, op dat moment was het quasi onmogelijk om genoeg van deze bagger te mining om aan de minimum amount voor withdrawal te geraken. Met andere woorden: je kon wel minen, je zag getalletjes verschijnen op je smartphone, maar je kon onmogelijk withdrawen

Het domein zelf heeft potentieel, maar je zal toch echt je inhoud grondig moeten herbekijken vooraleer er iemand links wil exchangen hoor... Persoonlijk zou ik mijn bezoekers nooit naar deze site willen doorsturen.
Als ik je een tip mag geven: begin opnieuw... Stop met achter elk artikel refferals proberen binnen te halen, begin met dingen écht te onderzoeken en schrijf lange artikels met informatie die écht nuttig is, en die niet iedereen in 2  kliks kan vinden. Wat je zéker niet mag doen is proberen mensen naar een ponzi te sturen, of naar een scam, of naar één of andere baggertoken zonder waarde... Sure, misschien klikt er wel een slachtoffer op zo'n link en je maakt enkele euro's buit, maar op die manier ga je nooit een vast publiek opbouwen waar je op lange termijn naar kan adverteren.
1420  Other / Meta / Re: BTT accounts Ban. on: June 18, 2020, 05:57:14 AM
The reason for the ban is usually stated when you(r friends) log in.

To be honest, your post looks like a preemptive strike in case somebody links your main account to your banned accounts. I'm not saying this is true per sé, but it sure looks like it from a bystander's point of view.

In case you want anybody to look into this, you'd better link to the forum profiles of the banned accounts...

And yes, this topic defenately belongs in meta... Please move it. In the altcoin discussion subforum you'll have less chance of getting an explanation.
